LR4, Dust Shoe Bristles, TPU Settings, 5 Walls instead of 1?

[azab2c]

Finally printing some long Bristles to help improve suction when cutting thin polycarbonate. I use 5 walls. But…

Noticed LR4 Kobalt TPU Bristles instructions on Printables mention “One Wall”. Which for me would print like… (note the print time and % of retractions)

However, during LR4 testing, I vaguely recall we found 5 walls was a nicer finish, faster and less retractions (a nice goal when printing TPU that clogs more easily) ?

Noticed same “One Wall” in descriptions for related Makita and DeWalt models:

• Makita 701 Tool Mount and Dust Shoe for the LowRider 4 CNC by V1 Engineering | Download free STL model | Printables.com
• DeWalt 611 Tool Mount and Dust Shoe for the LowRider 4 CNC by V1 Engineering | Download free STL model | Printables.com

Noticed pics for TPU Bristles available at V1E Shop have 1 - 2walls…

I usually print with 2, work pretty well if one’s not too stupid to correctly install the nozzle…

I printed with added perimeter wall count after studying the slice results and liked it.
